Auringonmassapurkaukset, often referred to as Coronal Mass Ejections (CMEs), are massive bursts of stellar plasma and magnetic field originating from the Sun's corona. These events are a form of space weather and can have significant impacts on Earth and other planets within the solar system. CMEs are driven by the sudden release of magnetic energy stored in the solar corona. This energy release can occur during solar flares, but CMEs are distinct phenomena with different characteristics and effects.

The ejected material typically consists of a cloud of charged particles, including electrons and protons, traveling at high speeds. These speeds can range from a few hundred to over a thousand kilometers per second. When a CME is directed towards Earth, it can interact with our planet's magnetosphere. This interaction can lead to geomagnetic storms, which are disturbances in the Earth's magnetic field. These storms can disrupt radio communications, GPS signals, and power grids. In extreme cases, they can pose a risk to astronauts in space and satellites.

The study of CMEs is crucial for understanding solar activity and its consequences. Space agencies utilize various solar observatories, both on Earth and in space, to monitor the Sun and detect potential CMEs. Early detection and prediction of CMEs allow for mitigation strategies to be implemented to protect technological infrastructure and ensure safety. While CMEs are a natural part of solar behavior, their power and potential impact underscore the importance of continuous research and monitoring of our Sun.
